    I find it mind boggling that you can 3d print rocket engines. I thought that the standard line is that 3d printing metal wasn't developed enough for anything serious. Not a mechanical/materials engineer, but if you can 3d print rockets what's off the table? Jet Engines and that's about it I think?

    From the article links, I am amused that SpaceX uses cybertrucks to tow their rocket engines around the grounds and not a normal cheaper truck. They also do it in a totally uncovered trailer, which must be good for the guys taking pictures for forums. But isn't that also good for guys taking pictures for competitors / Russians/ China?

      Beehive is 3D printing jet engines today, albeit small and potentially only going one way.

        Why would you want a yet engine to go backwards?

          I think by one way they are referring to cruise missiles i.e. the engine is only used once or twice. Once during test fire, and once in production environment.
